APPARATUS FOR SGBUBBING, MOPPINZG, AND POLISHING FLOORS.

' Application filed December 7, 1925. Serial No. 73,602.

United States, and residents of the boroughv of Manhattan, city, county,and State of New York, have invented certain new and usefulImprovements" in Apparatus .for Scrubbing, hfopping, and PolishingFloors, of which the following is a specification, sufficient to enablethose skilled in the art to which the invention appertains to utilizethe same.

The object of our invention is to afford simple but effective meanswhereby the surfaces of floors, etc., may be conveniently andexpeditiously cleaned and polished with a minimum expenditure of timeand effortin manipulation,--the invention consisting in the specificcombination and arrangement of parts and devices herein described andclaimed, whereby hand labor is practically eliminated as compared withpast methods, attained as In the accompanying drawings we illustrate apractical embodiment of the essential features of our invention, .in a

.paratus adapted to both washing and polis ing of floor surfaces,althoughwe do not limit ourselves to the identical form and constructionof parts shown herein by way of exemplification, since changes may bemade in minor details,-'and equivalent meping and polishing apparatus;Fig. 2, is a front elevation thereof, upon I line 33, F g. 1;

chanical expedients resorted. to, with like results, and withoutdeparting fromthe spirit and intent of our invention in this respect.

With this understanding X I Fig. 1, represents an elevation" of the leftside of our combined floor scrubbing, mopa larger scale;

Fig. 3, is a plan thereof, upon the same scale as Fi 2, and taken uponplane of Fig. 4, is an elevation in detail,- and upon a larger scale anddetached, ofthe inner side of the 'mop;

Fig. 5, is a transverse section taken plane of line 5-5, Fig. 4-; I Fig.6, is a central vertical sectional elevation, taken upon general planeof line 6-6, Fig. 3, but upon a larger scale, and broken upon " away inpart;

Fig. 7, is a plan or top view of the cylindrical brush member, detached;

Fig. 8, is a view of the under side thereof;-

Fig. 9, is a section thereof takemupon plane of line 9-9,' Figs. 7 and8. I Whatmay be designated as the basic support of our apparatus is thecarriage frame 'K, mounted u on a plurality of rollers k,

70, and prefera ly, although not necessarily,

.The brackets on which the rollers k, 7:, are

journalled support the carriage frame K,

a sufficient distance above thefloor F, to afford ample clearance, theintervening circumferential space being closed'by an apron d, of elasticresilient rubber, or equivalent material, adapted to effect a contactualseal with the floor surface and function as a dam for the retention ofwater within the area of the carriage frame F, as may be understood byreference more particularly to Flgs. 3 and 6, of the drawings.

.A bifurcated brace K, rigidly attached at its ends to the sides of thecarriage frame K, has rigidly attached to its apex the manipulativehandle H, which projects rearward and upward at a convenient angle, asindicated more particularly in Fig. 1, of the drawings.

of the carriage frame K, are bifurcated u rlght brackets K, K betweenwhich an electric motor M, is positioned, as illustrated Also rigidlyattached to. the side members more particularly in Figs. 2. and 3, ofthedrawings, in which 172., represents the flexible electric circuit cableprovided with the socket m, andswitch m a To the lower extremity of the"vertical shaft m (Fig. 6) of; the motor M, is rigidly secured a.rot-ative brush B, erably of circular "configuration all, the

prefbristles of whichfcontact simultaneously 1 with the floor surface,and indirectly con-V stitute the means of support for the .elec* tricmotor M, which latter thus functions also as a weight utilized 'ininsuring a substantial and effective coDtafitual engagement ofv thebrush bristles with the surface to be treated. To th-is'end, trunnionstuds m, m, on opposite sides of the motor M, protrude through verticalslots In", (one of which is shown in Fig. 6) formed for the purpose inthe upper portions of the aforei of the brush- B, constitutes the floorof a 're- 'ceptacle 12", the annular flange 6 forming said uprightbrackets K2, K2, of the carriage frame K, thus allowin the motor toadapt itself to stress and inequalities of floor surface, etc., in use.area of contact of the bristles b, of our rotary 'disc brush B, is adistinctive feature of our invention ascoinpared with the limitedperipheral contact" of the horizontal axis cylindrical brushesheretofore known and used in the art, which simply roll over the surfacetreated, whereas in our form ofbrush the contact of the bristles iscontinuous, and the motion horizontal as related to its vertical axis,thus utilizing the whole of the'bristle area of the brush.

What may be designated as the back 6',

thewall thereof; and this floor b, is per fora'ted and formed withextraneously protuberant spouts 12*, which are funnel-shaped.

internally to facilitate the discharge of water from said. receptacle6?, to the spaces between the bristles b, as'will be understood byreference more particularly to Figs. 8 and 9, of the drawings. a

S, is a splash hood rigidly attached to th I lower portion of the motorM, as shown more particularly in Fig. 6, of the drawings, and

formed with concentric flanges s, s, (Fig. 6,) which straddle theannular wall 6 of the .brush receptacle b and thereby confine the waterthereto and prevent external splash. Said splash hood S, is also formedwith a nipple and duct 8 for the attachment of a vother suitableabsorbent material secured by a clamp plate f, and screws f to a bracketk rigidly attached to said rear member k',"

of the carriage frame K.

,Wh en our apparatus is to be used for floor polishing the supply ofwater is of course omitted; and the mop F, may be removed temporarilyfrom its bracket k The manipulation and control of our apparatus issimple and convenient through the medium of the handle H, and connec:tions, and may be eflected by a person in upright position, therebyobviating the drudgeryand discomfort incidental to scrubbmg, mopping orpolishing by hand as heretofore.

While suitable for domestic use also, our apparatus. is especiallyadapted to the re The full broad quirements of public buildings,hostelries, factories, and office'buildings and other 10- calitieshaving large floor areas to be treated; and the results attained aremuch more effective and satisfactory than can be attained by hand labor,while the resultant economy of time and labor incidental to its use isan important factor of utility.

What we claim as our invention-and desire to secure by Letters Patent,is

1. In a floor scrubbing, mopping and polishing apparatus, a carriageframe, a motor mounted thereon for freedom of movement "in a verticaldirection relative to the frame within fixed limits, and a brush caringapparatus, the combination of a carriage frame, a floor contacting apronextending aroundsald frame, an electric motor mounted on said frame bymeans which permits limited vertical movement thereon, a rotary discbrush mounted on the lower extremit of the shaft of the motor, the discof said brush being perforated and formed with 'an upwardly extendingperipheral flange constituting a water receptacle, a splash hood affixedto the lower portion of the motor casing and formed with concentricflanges which straddle the said flange on the brush disc, and means forintroducing a liquid into said receptacle through said splash hood.

4. In floor scrubbing, mopping and polishing apparatus, a carriageframe, a floor contacting apron extending around said frame, an electricmotor mounted on said frame for freedom of vertical movement relative tosaid frame, a rotar disc brush mounted on the lower extremity of theshaft 01' the motor, the disc of said brush being perforated and beingformed with an upwardly extending peripheral flange constitutm therewitha liqmd receptacle, a splash hoo aflixed to the lower portion of themotor casing and formed with concentric flange! which straddle saidflange of the brush disc,

means for introducing a liquid into said receptacle through said splashhood, and a follower mop mounted on the rear of said carriage frame tothe rear of and outside of said apron.
